I know that someone else has to have had this same problem, but I've
been unable to find a discussion that's both on point and with a solution.
A new 20" LCD (Westinghouse L2045NV) has been purchased that has a
native resolution of 1400x1050. There is no monitor "driver" available
for that particular model, as far as I can tell.
There is no 1400x1050 option for "Screen Resolution" even though the
graphics card (Radeon 9200) should have plenty of memory to accomplish
it. I see no way in the (current) version of Catalyst to force a
specific resolution.
How can I get the system to drive the monitor at its native resolution?

I looked in my Catalyst Control Panel, and there is no 1400x1050,
even in the "Force..." submenu. The Force option, is for selecting
stuff outside the normal range. Your 1400x1050 is a 4:3 ratio, which
is great, but appears to be non-standard. If you run out of options,
try Powerstrip from entechtaiwan.com . It works with ATI and Nvidia
video cards, and has a custom resolution setting capability - that is,
if you can figure out how to work it.
Entechtaiwan, also has a moninfo application, which can be used to
examine the EDID info coming across the serial link from the monitor.
If the monitor supports DDC serial, then you may be able to see
a "mode line" in the displayed result, in the moninfo window. By
doing some simple arithmetic (subtracting adjacent numbers of
the mode line), you can get the front porch, back porch and
other assorted numbers. So maybe that is how you would go about
providing info for use in Powerstrip. I've exhausted my Powerstrip
trial period, so I can no longer experiment with it.
"Powerstrip can read the EDID data from your monitor and generate
a modeline -- videogen can not."
So it looks like Powerstrip should be able to populate the control
window by itself, with no math. You'd only need to learn about
this stuff, if using display devices with no DDC serial link,
such as projection devices.
Post back how it works out. Someone else might benefit.

If there's nothing in the Catalyst Contol Center that will
allow this res., try an nVidia card... just tried it on this
system with one (FX5700) and it supports 1440x1050 as a
custom resolution even with the now old 78.05 Detonator
version I have to use to keep the onboard tuner/capture
drivers happy.

That utility looks to be useful, but perhaps a bit to powerful for my
application. I'm looking for something fairly simple as this monitor is
for the daughter of a friend. I'll take a look at Powerstrip--maybe
there's a way to have quick settings, and hide the more complicated
parts of the interface.
A couple of other things I've found:
There are some guys that apparently have there own tweak version of
catalyst that has additional resolutions:

DOH!
I meant, 1400 x 1050, that is what I tried and it worked.

Ok, I tried the Omega Drivers and was able to get my monitor to show
1400x1050 @ 60Hz. Changing to any higher refresh would produce "no
signal." It looks like crap, so I went back to the original drivers.

Just to quantify "crap" a bit: The display looked like when you set an
LCD to just below its native resolution--mostly clean text with bands
intermittent bands of blurriness.

Maybe the actual mode it is using, isn't 1400x1050 ?
For whatever reason, maybe the actual video card hardware is running at some
other resolution. Short of using an oscilloscope, I don't know how you can
easily verify what the output of the video card is doing.

While it would be more difficult to determine actual output
resolution without hooking up another monitor capable of
1400x1050 or larger res (and even then, a bit of a pain to
determine if it's really exactly 1400x1050 except maybe if
some kind of 2x2 grid image were displayed then checked for
uniformity, one way to get some idea if the driver is at
least *trying* to do it would be to just do a screencapture
(Print Screen Key) while in that video mode and open it
(paste clipboard into) an image editing app to see what the
reported dimensions are.
I also wonder if there are some menu settings on the monitor
that might control related settings.
